摘要： An optical resonator type organic electroluminescent element has a multilayered film mirror 30, a transparent electrode 12, an electron hole transportation layer 14 and a luminescent layer 16 configuring an organic layer, and a metallic electrode mirror 20, formed on a glass substrate 10. The optical resonator type organic electroluminescent element amplifies a specific wavelength (especially, in a range of about 30 nm toward a shorter wavelength side from a luminescence peak wavelength of the organic layer) in luminescence light by a minute optical resonator, which comprises the multilayered film mirror 30 and the metallic electrode mirror 20. It is determined that the minute optical resonator has an optical length L which is twice as long as a resonance wavelength, the organic layer has a thickness of 100 nm or more, and the transparent electrode has a thickness of 50 nm or more or a thickness so to have a sheet resistance of 30 &OHgr;/□ or less. Thus, the transparent electrode can be prevented from generating heat even when a large current is caused to flow into it, and the element characteristics can be reliably prevented from being deteriorated. Moreover, the reliability of this element can be improved because the organic layer containing the luminescent layer has a sufficient thickness.

摘要： 4-Cyanocoumarin derivatives which have a distinct sensitivity to visible light, distinct luminescent ability, and satisfactory applicability for photochemical polymerization, dye lasers, and organic electroluminescent elements. Since most of the derivatives have a fluorescent maximum wavelength of 600 to 650 nm, particularly, 610 to 630 nm, they are extremely useful as luminescent agents for organic EL elements which emit visible light in a red-color region, and can be quite useful as luminescent agents in organic EL elements and laser-active substances in dye lasers, as well as luminous bodies as lighting sources for lighting devices, and information displays for visually displaying information.

摘要： An organic EL element has an anode, a cathode, and one or more organic compound layers sandwiched between the anode and cathode, wherein at least one layer of said organic compound layers includes an organic compound denoted by chemical formula (1), which is more specifically denoted by chemical formulas (2)-(5). By introducing desired substituents at R1-R4, these compounds can be made to demonstrate hole transport function, emissive function, electron transport function, or a combination of those functions. Due to its tendency to be structurally non-planar, the organic compound does not crystallize easily, and has a high glass transition temperature. Use of such a compound in an organic EL element enhances element life.

摘要： The invention provides electroluminescent (EL) elements, such that a red EL light source, a green EL light source and a blue EL light source emit red color light, green color light, and blue color light, respectively, and are disposed at the rear of liquid crystal display elements. Each EL light source includes an organic EL element in which an organic thin film emits light. Each EL light source has a structure in which an organic luminescent layer is sandwiched between an indium tin oxide (ITO) electrode and a metal electrode which have striped patterns which are orthogonal to each other, and sections (luminescent sections) at which the striped patterns of the ITO electrode and the metal electrode intersect with each other emit light. The luminescent sections are arrayed two-dimensionally on a glass substrate and illuminate the entire display area of the liquid crystal display element.

摘要： A micro-optical resonator type organic electroluminescent device utilizing an organic electroluminescent material high in emission efficiency but broad in emission spectrum width, has a narrow half bandwidth in the emission peak and a superior forward directivity and an excellent monochromaticity in light not separate into components, wherein a micro-optical resonator is formed by a multi-layered mirror and a metal mirror. The optical length of the micro-optical resonator, calculated from the total thickness and the refractive index of a transparent conductive layer and a luminous layer placed between the multi-layered mirror and the metal mirror and also from the light penetration depth into the multi-layered mirror, is 1.5 times the wavelength of a desired light emitted from the device, and the desired light is set on the short wavelength side of the emission spectrum of the electroluminescent material.
